Abstract
Purpose
This study aims to investigate the relationships between distributed leadership, teacher academic optimism and teacher organisational commitment with the contextual influence of gender and teaching experience.
Design/methodology/approach
This study employed partial least squares structural equation modelling for data analysis. This study has selected 421 teachers from 18 secondary schools in Penang.
Findings
Distributed leadership has a positive direct effect on teacher academic optimism and organisational commitment. The relationship between distributed leadership and teacher academic optimism was stronger for male teachers and senior teachers who have more than ten years of teaching experience. However, gender and teaching experience have no significant moderating effects on the relationship between distributed leadership and teacher organisational commitment.
Research limitations/implications
The reason for the non-existent relationship between distributed leadership and teacher organisational commitment across gender and teaching experience remains unknown. In-depth investigation using interview method is required for further exploration.
Practical implications
This study complements and extends prior research on the relationships between distributed leadership, teacher organisational commitment and teacher academic optimism by providing evidence from Malaysia on how they contribute to the organisational conditions of their school.
Originality/value
This study has its originality in investigating the relationships between distributed leadership, teacher organisational commitment and academic optimism with the contextual influence of gender and teaching experience in the non-western society.

Abstract
Purpose
Data envelopment analysis (DEA) and analytical hierarchy process (AHP) are two widely applied methods to evaluate and rank suppliers in terms of sustainability. In this study, to investigate the extent to which potential differences in the outcomes of these two methods influence the benchmarking strategies, a comparative analysis based on a common set of data gathered from 19 logistics service providers is implemented.
Design/methodology/approach
As suppliers' sustainability cannot be improved in a single-step process due to several limitations, improvement needs to proceed gradually. Therefore, using the self-organising map method, the suppliers were classified into clusters within a novel framework for gradually improving their sustainability. Then, the two processes of gradual improvement based on the outcomes of DEA and AHP were compared.
Findings
The findings show that although the rankings of suppliers guided by the methods correlated to a high degree, the benchmarking strategies provided by the methods for gradually improving the sustainability of suppliers differed considerably. In particular, whereas AHP suggests a benchmarking policy better suited for unsustainable or less sustainable suppliers with limited access to resources, DEA proposes one for suppliers able to dramatically boost their sustainability with few quick, significant leaps in performance.
Originality/value
First, this study revealed a novel gradual improvement framework using the self-organising map method. Second, it clarified the extent to which the benchmarking policies are influenced by the type of evaluation method.

Abstract
Purpose
The paper aims at providing a survey of the development of empirical research in business process management (BPM). It seeks to study trends in empirical BPM research and applied methodologies by means of a developed framework in order to identify the status quo and to assess the probable future development of the research field.
Design/methodology/approach
In order to analyse the development of the research field a systematic literature review of empirical journal articles in the BPM context is conducted. The retrieved literature is analyzed by means of scientometric methods and a developed reference framework.
Findings
The steadily growing number of published articles in empirical BPM research shows an increase in interest in the research field. Research interests, applied methodologies, the underlying research paradigm and the level of maturity of empirical BPM research differ depending on regional aspects. BPM gains importance in the industry as well as in the public administration context.
Research limitations/implications
The findings are based on a sample of 355 articles and not on an exhaustive amount of available empirical research contributions. Nevertheless, significant analyses can be conducted. Future research could apply the developed reference framework for further literature reviews in order to be able to compare the findings and to measure progress.
Originality/value
The presented literature review gives an overview of trends in empirical BPM research. The developed and strictly applied reference framework supports a systematic analysis of contributions and can thus draw a significant picture of the state‐of‐the‐art of the research field. To the best knowledge of the authors no such survey has currently been undertaken.
